I read this article with some concern and its theme surprised me. My S is in a PhD program and he seems to be doing fine but we do have mental health issues in our family.
He is by nature an introvert so I am concerned in general that he spends a lot of time alone. He spends a lot of time grading papers and teaching and he goes to the gym a lot. He’s not too excited about classes but he can’t wait to do research.
He’s always been the type to sit around and think Big Thoughts about physics, math, and philosophy. I thought grad school would be perfect for him because he’d be allowed to be thinking about physics 24/7 as a job.
I’ll have to show him this article and see if any of it rings true to him.
